Working in gedit

• Last week I worked in a new implementation for the drawspaces plugin of gedit. Now as you can see in the gedit-plugins repo, it was ported to c and now it is using the new drawing style implemented in gtksourceview 2.4.
• Another thing I did is port, the missing plugins to gtkbuilder and the terminal plugin to gio, so gedit is not using libglade and gnome-vfs anymore in the gedit-plugins repo.
• Finally, I added a new feature, so now you can write +N or -N in the jump to line widget and it is going to jump to the relative line at the current one.
